Step 1:Without lifting or handling the objects in your bag, estimate their mass in grams.

Record your data in the upper part of your Data Table under 1st Estimate

Step 2:Lift each object up and handle them to estimate the mass of each in grams.

Record your data in the upper part of your Data Table under 2nd Estimate

PROCEDURE – PART 1

Page 9: Measure for Measure

Step 3:Learn How to Use a TBPBUse a Triple Beam Platform Balance to calculate the actual mass of each object

Record your data in your Data Table under Mass

PROCEDURE

Step 4 In this step you will measure the length of each

object HOWEVER, you may NOT use a standard unit (cm,

in, etc.) you MUST use unconventional units Horse length – 13 index nails

Record your data in the lower half of your Data Table under 1st Measurement

Step 5 Measure the length of each object with a standard unit

of measurement – cm on a ruler Record your data in the lower half of your Data Table

under 2nd Measurement
